Financial News APIs
Financial news APIs tag articles by stock ticker and score sentiment, so a story can feed a trading or research tool directly. MarketAux tags tickers and entities with per-article sentiment, and Finlight adds company extraction and a live WebSocket feed. AlphAI and XFINLAB go past news into insider trades, macro events, fundamentals or FinBERT sentiment. All are freemium with a key.

Choosing a Financial News API
Is there a free Financial News API?
Yes. MarketAux, Finlight, AlphAI and XFINLAB have a free tier alongside paid plans.
Which Financial News APIs work without an API key?
All of them need a key or account. MarketAux, Finlight, AlphAI and XFINLAB give one out free when you sign up.
Can I use Financial News APIs in a commercial project?
XFINLAB permits commercial use. MarketAux and AlphAI restrict it, for example to non-commercial or attributed use, so read the terms first.
Which Financial News APIs work with AI agents?
Finlight has an MCP server, so an AI agent can call it directly. AlphAI publishes an OpenAPI spec for generating clients and tools.
